State Dependence of Krylov Complexity in CFTs
Arnab Kundu, Vinay Malvimat, Ritam Sinha
We compute the Krylov Complexity of a light operator in an eigenstate of a CFT at large central charge . The eigenstate corresponds to a primary operator $\…
RG flows on two-dimensional spherical defects
Tom Shachar, Ritam Sinha, Michael Smolkin
We study two-dimensional spherical defects in d-dimensional Conformal Field Theories. We argue that the Renormalization Group (RG) flows on such defects admit the existence of a de…
A model of persistent breaking of continuous symmetry
Noam Chai, Anatoly Dymarsky, Mikhail Goykhman +2
We consider a UV-complete field-theoretic model in general dimensions, including , that exhibits spontaneous breaking of continuous symmetry, persisting to arbitrarily large…
Long-range fermions and critical dualities
Noam Chai, Soumangsu Chakraborty, Mikhail Goykhman +1
We construct long-range fermionic models with the Gross-Neveu and Gross-Neveu-Yukawa interaction, and argue that their critical regimes are equivalent. To this end, we calculate va…

Dario Benedetti, Nicolas Delporte, Sabine Harribey +1
We study bosonic tensor field theories with sextic interactions in dimensions. We consider two models, with rank-3 and rank-5 tensors, and and symmetry, res…

Shiroman Prakash, Ritam Sinha
We study tensor models based on symmetry groups constructed out of rank- tensors with order- interaction vertices. We refer to those tensor models for which …
On The Evolution Of Operator Complexity Beyond Scrambling
J. L. F. Barbon, E. Rabinovici, R. Shir +1
We study operator complexity on various time scales with emphasis on those much larger than the scrambling period. We use, for systems with a large but finite number of degrees of…
Dual Superconformal Symmetry of Chern-Simons theory with Fundamental Matter at Large
Karthik Inbasekar, Sachin Jain, Sucheta Majumdar +5
Dual conformal symmetry and Yangian symmetry are symmetries of amplitudes that have aided the study of scattering amplitudes in highly supersymmetric theories like SYM…

Shiroman Prakash, Ritam Sinha
In this note, we study a melonic tensor model in dimensions based on three-index Dirac fermions with a four-fermion interaction. Summing the melonic diagrams at strong coupling…

Adwait Gaikwad, Ritam Sinha
We consider Random Matrix Theories with non-Gaussian potentials that have a rich phase structure in the large limit. We calculate the Spectral Form Factor (SFF) in such models…

We consider time-dependent entanglement entropy (EE) for a 1+1 dimensional CFT in the presence of angular momentum and U(1) charge. The EE saturates, irrespective of the initial st…
